Le esperienze di scuole all'aperto in Italia nel primo Novecento. Avvio di un'indagine
No full textIl contributo affronta il tema delle scuole all'aperto dei primi del Novecento come movimento internazionale, soffermandosi sulle scuole all'aperto in Italia, ancora poco esplorate dalla storiografia educativa, per poi concentrare l'attenzione sullo studio di caso di Bologna. Il contributo s'inserisce nel dibattito attuale sull'outdoor education
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Ostrich Fern Fiddlehead (Matteuccia struthiopteris L. Todaro) Cultivation: Controlled Environment Requirements and Growth Cycle Compression
No full textOstrich fern (Matteuccia struthiopteris L. Todaro) fiddleheads hold considerable potential as a nutritious, traditional, local food source in Canada. However, fiddleheads are only available for a few weeks each spring. Development of the industry can only be accomplished with indoor production that recreates and optimizes the outdoor seasonal cycles. This study investigated environment conditions for indoor production and the potential for compressing the growth cycle to achieve quicker harvests. Measurements of canopy net carbon exchange rate showed that carbon exchange in adult fronds was maximized at 400-600 µmol m-2s-1, with aerial conditions of 1300-1600 ppm CO2 and 18-23oC. Experimental modification of the growth cycle revealed that dormancy can be completed in 9-12 weeks, while a full 18 weeks of recharge after emergence is critical. These findings suggested that commercial production is feasible, and the growth cycle may be reduced to 214-238 days
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
"This School Called Life". The Adult Education of Paulo Freire amid Risk and Extraordinary Effort
No full textThis chapter presents an interpretation of Paulo Freire’s educational conception starting from the analysis of the writing This school called life (1985), in which it is possible to find framework elements (equation of education and life, dialogue, autobiography) and contents (formative role of experience, opposition to fatalism, transformative action in real life) that contribute, even today, to define meaning and role of adulthood and adult education. In this perspective, it is interesting to highlight that the Freire’s legacy is still a fruitful contribution on lifelong and adult education. We are referring, for example, to the topics of hope, emancipation, transformative practices of adult people who live and participate in their historical context, supported by an education that, starting from the literacy, becomes a constant in their efforts of social actions. The learner par excellence of Freire’s education is the adult person: the adulthood is assumed in its dimensions of consciousness, knowledge, experience, relationship, identity and role as elements that realize a real humanity. Freire affirmed that “Life as a whole taught me as a great lesson that it is impossible to live it without risking”. In the writing This school called life, the notion of risk is deepening in three directions: learning by acting and making mistakes; not receding to fatalism; not giving in to the consolatory and paralyzing role of fantasy and imagination. For this reasons, the “school of life” needs of the school in the strict sense, as a public institution that is a forerunner of adult education. Freire does not confuse these two entities: making life a school is possible precisely because, rationally, people know the meaning and function of the school. This in order to pursue a feasible dream of democratic society, where people have a voice, taking charge of the fantastic effort that it requires
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
